Questions regarding Aspen simulation for gas separation units
Thread Content
It is based on the raw material components and operating conditions entered during actual operation, but both the top and bottom temperatures of the depropanization tower are about 3-4 degrees lower than in reality. I’d like to ask how to adjust it
Also, without any design specifications, this process is convergent; however, once design specifications for the content of heavy components at the top of the tower and light components at the bottom are introduced, the process can no longer converge
By changing the material property method, the design specifications were met, but the temperature remains low
